Hi, few weeks ago I was coughing a lot (it lasted over 3 weeks) and generally felt very week. I had xray that said There are prominent central bronchovascular markings in the infrahilar regions which may be acute or chronic. There is slight left hilar fullness. I got ZPack from my doctor and was ordered to take it for 5 days. No other follow up was ordered. I feel better, but I still feel week (it s been 2 weeks since I finished the meds), my back continues to hurt and I occasionally still cough. Is the Xray suggesting something more serious than the infection? Should I follow up in any way? Thank you.
